For storing data in computers, magnetic tapes and hard disks are used from seventy year. In between these years, there are many other technologies which have been introduced for controlling data storage magnetization which can be the first choice of the public due to its low prices and higher longevity. RAM i.e. Random Access Memory are used as the main and basic memory for data processing in computers as technologies with magnetic storage are considered inadequate. It defines high energy consumption with low writing speed.
By using novel techniques, with fast and no energy wasting, magnetic storage can be achieved. There is a magnetic inversion without the use of coils. Technologies with the storage of traditional magnetic data carries data with disk or tapes by using cobalt alloy. A magnetic field is generated from the coil which carries current. It helps in the changing of direction which uses very small portion of data carrier with magnetization. This procedure or process has a very low speed when compared with the modern processors. It helps in the generation of electrical coil resistance which further leads to loss in large amount of energy.
By using coated semiconductor, an electric current is passed to the inverted magnetization which results in a tiny metal dot. This is the result of physical effect known as spin-orbit-torque. It results in electron accumulation through the flowing current in a conductor at the edges of the conductor created from the opposite magnetic moment. The spinning electron will further create a magnetic field which results in nearby magnetic material i.e. atoms, which also helps in the change of orientation in magnetic moments. A new study has been performed by the scientists who show the working process in detail with its speed. These results were published in various journals.
Along with this, an experiment is performed in which magnetization of cobalt dot is inverted with the diameter of 500 Nanometers. It also uses electric current pulses which can be flowed through adjacent platinum wire. While performing this experiment, cobalt dot are exposed with the focus in x-rays. It creates a Swiss light source of PSI. It helps in the successfully scanning at a specific point which is entirely dependent on the local direction of magnetization. Also, image of magnetization dot with two-dimensions helps in the gradual changing of current flowing pulse.
By these techniques, researchers are able to observe the inversion of magnetization which can be happened in less than one nanosecond. It is considered a much faster than other studied experiments and technologies. On the basis of these experimental parameters, an accurate prediction can be made about the beginning and ending of magnetization inversion. Also, the other techniques used inversion which is primarily driven by the electric current and triggered by thermal fluctuations occurred in the material, which causes large variations in the inversion timing.
